Innosilicon T2T 30T review

[Procaius]

Well... after an absurdly long wait (miner ordered June 28th directly from Innosilicon), my T2T 30T finally arrived on August 12th.  The stupid courier actually left my miner on the front steps of my house (while I was 1500 miles away on vacation).  Thank goodness my neighbor wasn't far and picked it up for me.

The miner is running very well.  Averaging 26T in balanced mode with an average temperature of 58 celcius.  The miner came loaded with the latest August firmware which was nice.   No update required just plug & play.

Why do people deliver like that? LOL

Interesting as I had the same batch as you but had to upgrade to '7th of August 2019 07:03 AM' as the preloaded one was 1 weak earlier (1st of august or something). On the downside, the previous version was doing 29.5ths in factory settings, the new one only 29 

I am doing factory settings and hoovering around 29ths at 80 to 82 degrees but at 2450W ~ 2500W at the moment.

How many Watts do you pull from the socket?

[philipma1957]

innosilicon  usually misses specs

so 2500 watts at 29 th  is about what to expect for gear rated  30th  and 2200 watts.   if you are in a cold spot like 70f or 20c

you would be closer to  2200 watts and 30th


their gear tends to work without breaking.  and they have been known to deliver late.

Welcome to the world of  asic builders.  late and off spec  is common.

a lot of asic gear runs better in a 15-20c room  or a 60f-70f room

It does seem like a rock solid unit, I put emphasis on rock as it is heavy as F**K.

I'm in northern Canada with cool temps so I bumped mine up to Performance+ shortly after posting my original message and now its average hash rate is 30.04 and chip temp is averaging 68 degrees celcius with fan speed at 65%

I currently don't have any way of measuring what wattage it's gobbling up and frankly I don't wanna know!   

[AlecMe]

For the low temperature of 16 - 20 Celsius I can only say: Winter is coming   soon

How did you get the fan to 65%? I believed they are 'blocked' at 100%.
I am curious how many W's you are pulling  

Also, managed to reduce the vibration from it (and decibels by almost 10) by putting rubber legs (found on an old fridge compressor) under it.

Always nice to meet another one, though I'm really only north of Ontario these days. So far your delivery experience sounds like anything I ever receive from DHL, someone has to be home, they even mess up my hold don't deliver requests.

If you do get curious about your power draw here's something I rigged up to measure my gear. 220/240V North America power meter - DIY Under 60$ CAD
This is locked for now but here's how I've managed my winters, The winter mining setup so far, might be at half capacity by October the way things are looking this year.

Believe it or not I built an 8' x 12' shed and had it professionally wired for 240 volts.  I've been running miners in it for about 12 months now and it works great.  Even throughout our frigid Canadian winters.  That is how I kept the fan at 65%, the day I wrote that post it was like 12 degrees celcius outside (53 f).

One of the reasons I put it in the shed is the noise, the other is the heat.  Believe it or not we do get some pretty warm days, even up here in Northern Canada.

I'll have to look into building that meter, thanks.  I love DIY stuff and electronics (which is why I got into mining in the first place).

I'm in northern Alberta.  Very nice to meet you as well.

One update on temperature:

I've changed the exhaust ducting from a 4" (was waiting on the other one to be delivered and this was the only one available) to a 5".

Overnight around 14 degrees outside and a good airflow I've managed to get 65/67/67 degrees on the boards with the fans at 95% (first time ever, but still room for improvements) down from 76 to 84 degrees.

The interesting part is that the miner shows 28 th/s now (still on factory settings, just a restart involved - guess is it now outside its +-5% tolerance), but will check the pool after 24h due to the restart.

I might try and post my fridge build, as I am mining home in a back spare room and managed to reduce the noise relatively well.
Of course, if there is interest

[Procaius]

These things love a LOT of air flow.

I built a silencer box inside my shed out of drywall and I keep it cool with 6" ducting and this 440 cfm 6" exhaust fan:

[philipma1957]

that link has a six inch and an eight duct fan.  I suggest doin two of these miners and using the eight duct fan to pull air out.

Nice, I wish I could get power rates like you guys or at least have options for providers. I was actually Jasper this past March, beautiful drive up from Edmonton.

If you get around to it you should post some images of your setup, we always like seeing new ones. This is what I set up for my garage this year Summer Mining - Home miner.

Hi guys,  somebody could upload video or pic  with Wattage metter at-the-wall  for T2T 30TH model ?  thanks!

[AlecMe]

2360W at the moments with 22 - 23 degrees celsius room temperature, plenty of 'fresh' air, vent at 100%   , 28.12 th/s, board temp 67/69/69 uptime 9h (due to power failure, was 10ish days prior at almost 28.7th/s).

It might be a good workhorse but the vent is driving me away from linking it  

Edit: factory settings at the moment.

[judypug1956]

are you on factory setting for the 2360/28.12

pretty typical for inno off 5-10% on power and off 5-10% on hash

you should try

 balanced
 Balanced+
 Balanced++

Every inno I have owned has been off 5-10% on power and 5-10% on hash

they all like balanced better then factory unless room is stupid cold
they all run the fans too fast.

I am waiting on that 50t  to ship so far it is two days late.

Do you have any stats for

Balanced++
Like Th/s and watts, please?

Hi, almost 2400W,  so its the T2THF model, right ?  with dual fan in front....  the T2TZ model its 72W/T chip  (2160W)

[AlecMe]

This is from the Overview tab:

Type T2TZ
Controller Version soc
MAC Address *****
Build Date 7th of August 2019 07:03 AM
Platform Version t2tz_soc_20190807_070310

It has 2 fans at the back (the way out) and only 1 at the front - the big one - where the power cable and LAN are.

[Procaius]

According to SVpool.com I'm getting 33.78 TH/s in performance mode.  Can't complain about that!

[AlecMe]

Did anyone try putting these in dielectric liquid?

I am curious how to trick the fan presence for the MB

The same way one simulates the fan(s) on any miner - by making or purchasing a fan simulator. Search Amazon et al for them. Another way would be to get some old fans, cut off the blades and run the fans in the fluid (but out of the way of flow) with just the hubs spinning.
